Application October 26, 1942, Serial No. 463,374

3 Claims.

This invention relates to window construction, particularly to a parting strip and weather strip for windows and has for an object to provide a device of the character designated which shall be adapted to hold a window sashfirmly in place without binding, and which shall be weather and waterproof.

A further object of my invention is to provide'a parting strip which shall be adapted to guide'the sash both normal to the face of the sash and parallel thereto, and which shall be at the same time an effective weather strip.

vA still further object of my invention is to provide an effective weather strip for windows, which may be applied without the necessity of removing the sash from the window frame, and which shall be simple of design, easy to -manufa'cture and install.

- Preferably, my invention contemplates, in place of the ordinary parting strip used with double windows, a parting strip made of spring metal, substantially U-shaped in cross section with resilient concave sides which shall be adapted to cooperate with resilient strips of congruent shape attached to the window sash, and thus serve as guides for the sash both normal to the plane of the face of the sash and parallel thereto. It is also contemplated that I will employ a fixed stop along one side of the window and an adjustable stop along the other side whereby the sash may be adjusted so that the strips on the sash, and the sides of the parting strip shall be maintained in snug but yielding engagement.

A window embodying features of my invention is illustrated in the accompanying drawing forming a part of this application, in which,

Fig. 1 is an elevational view of the window;

Fig. 2 is a fragmentary elevational view of the upper corner of a window sash and frame with parts broken away and drawn to a larger scale than Fig. 1;

Fig. 3 is a sectional view taken along the line IIIIII of Fig. 1;

Fig. 4 is a sectional view taken along the line IVIV of Fig. 1;

Fig. 5 is a sectional view taken along the line VV of Fig. 1 and showing the adjustable stop and the weather strip between the meeting rails of the sash; and

Fig. 6 is a sectional view taken along the line VI--VI of Fig. 1.

Referring to the drawing I show a window frame indicated generally by the numeral II] in which are mounted an outer, or upper, sash ll and an inner, or lower, sash l2. The sash H and I2 are held in the frame bymeans ofan outer, fixed stop I3 and an inner adjustable stop M. The position of the inner stop 14 may be adjusted by means of screws I6 which'pass through elongated slots or holes I! into the frame H3. The sash H and [2 are provided with meeting rails I8 and I9 respectively which havejthe usual inclined meeting surfaces. A pliable metal weather strip 2| ispreferably attached to, the meeting rail Hi to seal the joint betweenth'e strips when they window is closed. See'Fig 3.

The bottom rail of the sash I2 is shown in Fig. 6 at 22, and a pliable weather strip 23 is shown attached thereto. At the top of the window is shown the usual top parting strip 24 to whichis attached a pliable, weather strip 25 to seal; the top rail 21 of the sash ll whenithe sash I1 is raised. I

Between the sash and I2 along each side of the frame [0 Iiinsert my improved combined parting and weather strip 28. Asmay bestlbe seen in Fig. 3, the parting strip is made of spring metal substantially U-shaped in cross section and is formed with concave sides 29 and 3| free to flex and extending into the space between the sash l I and I2. As is the usual practice in window construction, the parting strip is mounted in a groove 32 in the window frame In and is held in place by means of a suitable number of nails 33 so that it is firmly anchored in place. The base of the strip seated in the groove 32 is preferably of cross sectional dimensions equal to those of the groove provided in the frame for the wooden parting strip usually employed in window construction and which is /2 inch wide by T5: inch deep. weather strip may thus be substituted for wooden strips in already existing construction, as well as be employed in new construction.

Coacting with the resilient concave sides 29 and 3! of the parting strip are weather strips 34 and 36 which are secured along one edge respectively to the sash II and I2 by means of small nails 31 and 38. The strips 34 and 3B are made of spring metal and are shaped to provide resilient convex sides 39 and M which are congruent to the concave sides 28 and 3| of the parting strip 28. By thus shaping the strips 34 and 36 and the sides of the parting strip 28 and making them of spring metal I provide guide means which remain in snug engagement at all times and. which are effective to hold the sash against movements both in a direction normal to the My improved parting andplane of the face of the sash and in a direction parallel thereto.

To install my improved weather stripping in an already existing window construction, the usual parting strip is removed from the groove 32 and my improved parting strip 28 is inserted therein on both sides of the Window frame. Thi may be done without removing the sash H and I 2 from the frame. The strips 34 and 36 are then attached to the sash as shown, the sash being centered with respect to the frame so as to leave a small space along the edges as shown in Fig. 3. The action of the weather strips 34 and 36 and parting strip 28 prevents any ingress of air or water around the sash, and the space between the sash and frame prevents any binding. Also.

the coaction of the weather strips and the parting strip hold the sash against lateral movements. The adjustable stop It is so placed that there is a pressure on the spring metal forming the parting strip and the weather strips 34 and 36, thereby insuring a weather tight fit. The weather strips at the bottom and top of the sash and along the meeting rails are applied as shown by means of small tacks or screws. It will be seen that my improved parting strips-and weather strips may be applied without removing the window sash from their openings or refitting the sash to the openings. This is very important where they are to be applied to already existing construction. When assembled, it will be apparent that I provide an improved, combined, parting strip, guide, and weather strip which, in cooperation with other weather strips, insures an easily operated, noiseless, weather tight window.

While I have shown my invention in but one form, it will be apparent to those skilled in the art that it is not so limited, but is susceptible of various changes and modifications without departing from the spirit thereof, and I desire, therefore, that only such limitations shall be imposed thereupon as are specifically set forth in the appended claims.

What I claim is:

1. In a window embodying a frame with cooperating sash, a parting strip interposed between the sash and formed of spring metal U shaped in cross section with the free ends of the U extendin% between the sash, concave resilient side on the parting strip facing the sides of the sash and extending into the space between the sash, and Weather strips on the sash having resilient convex sides cooperating With the parting strip, said resilient weather strips fitting into the concave sides of the parting strip and being secured to the sash.

2. In a window having a frame and upper and lower sash in the frame, a resilient metal parting strip U shaped in cross section mounted in the frame between the sash and extending throughout the length of the frame with the free end of the U extending between the sash, and having concave sides facing the sides of the sash and extending from end toend thereof between the sash, and resilient congruent metal weather strips each secured along one edge to the opposed sides of the sash and each having one side extending free between the opposed faces of the sash and a convex surface fitting snugly in the concave sides of the adjacent parting strip. 7

3. In a Window having a frame and upper and lower sash in the frame, a resilient metal parting strip mounted in each side of the frame, said parting strip being U shaped in cross section with the closed end of the U fastened in the frame and the sides of the U extending free between the opposed sides of the sash, and having concave faces facing the adjacent sash, and resilient metal weather strips each secured along one edge to the opposed sides of the sash and each having one side extending free between the opposed faces of the sash and fitting snugly in the concave face of the adjacent side of the parting strip.
